1 Claim. (Cl. 126-350) This invention relates generally to water hee .g appa ratus and more particularly to water heating apparatus having novel means for supplying heated water.

The invention has for an object the provision of a device of the class mentioned which is of simple, durable construction, desirable and eliicient in action and which can be manufactured and sold at a reasonable cost.

The invention proposes the use of a water boiler provided with a superheated water or steam outlet pipe which may be connected for example with a container holding coffee or the like, and arranged for directing the superheated water or steam thoroughly and completely therethrough to make coffee.

The device is provided with means for heating the boiler and for manually shutting olf part of the boiler so that the water in the lower part will beco.. e superheated and will pass through the connection and into the container as for example to extract coifee.

Por further comprehension of the invention, of its objects and advantages, reference will be had to the following description, accompanying drawings and to the appended claim in which the various novel features of the invention are particularly set forth.

ln the drawings:

Figure 1 is a front view of my device taken in crosssection;

Figure 2 is a top view taken on line 2--2 of Figure l; and

Figure 3 is a view taken on line 3-3 of Figure l.

Referring speciiically to the drawings, the water heating apparatus comprises a tank l supported by legs 2 from a base 3. The tank l has a top cover t and a bottom plate 5 which supports a heating element o and a thermostat 7. in the lower half of the tank l is a partitioning member 3 supported by flanges 9 extending inwardly from the sides of the tank l which divides the tank l into two compartments A and E. A water level indicating tube l is disposed on the outside of the tank l. rl`he tank partitioning plate has an opening il formed therein which opening allows ready communication between portions A and B of tank l.

Centrally located on the underside of partitioning plate S is located a valve 12 extending downwardly into section B of tank 1. A valve operating member .i3 extends upwardly from valve l2 through compartment A of tank 1 and the top plate 4 to form a handle 13a, as shown in Figure l. A gasket 3.4 acts as a bearing for shaft 13.

Valve l2 includes a spout portion l5 extending through the side wall of tank 1, portion B, which is concentrically hollow to accommodate valving member 16 which is held in place by nut 17 at its lower portion. A hole l extends through the valving portion 16, as shown best in Figure 3, so that upon correct alignment of the hole and the bore in member 5, the liquid in chamber E is permitted to flow out of the chamber and for example, as set forth for the specic application shown herein, into container generally indicated at i9.

On the upper side of compartment plate is a plate- "nted' States Patent ICC like member 20 attached through a raised hub portion 2da to the valve stem 13 by means of set screw 2l. lt is therefore apparent that movement of the valve handle 3a will cause pivotal movement of the member 2t? to cover or uncover, as the case may be, the opening 1l of partitioning member 8. Stops Z2 and 23 are provided on plate S to restrict the valving movement of member 2li.

A aldil-Le member is attached by means of set screw 2S onto shaft i3. This funnel is of such a size that projects beyond the vertical projection opening 1i in plate ti so that steam bubbles rising through the opening are entrapped thereunder. Plate 2li is not intended to form a steam tight t with the opening il and any steam which does escape into compartment A is caught under the hood and retained thereunder until sufciently cooled by the surrounding water to be dissolved therein. Container 19, attached by any known means the end of spout 15, may be specifically adapted for Lle to hold coffee grounds 25 with suitable filter means at the bottom to prevent egress of the grounds and allow the liquid coffee to drain therethrough. At the lower end of chamber 23 spout Z9 which is adapted :o communicate with a coee pot or cup depending upon how much is being drawn from the Coffee maker.

iie operation of the device is as follows:

Both chambers A and l of tank l are filled through ylling tube 36 with water up to any readily discernable cpth as shown by gauge it?. Filling tube 3l? is then o Vred by tube cap 3i to prevent foreign matter from entering the chambers. Communication by means of opening is per. .iitted between the two chambers and the heater 6 supplies the necessary energy to the water to substantially heat it to its boiling peint.

For the above mentioned specific adaptation when it is desired to draw a cup of coffee, or any other amount of coffee, container 23 is filled with grounds corresponding to the regular well known coffee-water ratio. r"hen the valve handle lrz is rotated so that opening il is covered by plate Ztl, thus partitioning chamber A from chamber E, and at the same time opening valve le, permitting water to flow from the chamber B and in the case of the aforementioned speciiic application, through the grounds containing compartment 23 and into a cup or other container. The water `vill not ilow at the instant the valve is opened since the pressure of the water in chamber A has been dissociated from that in chamber l2 following the closing of the cover plate 2.o. Although cover plate 20 does not form a steam tight fit with the partitioning plate 8, it sufhcienly precludes instantaneous ilow of water from chamber A to chamber E due to the water pressure exerted on cover plate 2t? by the water disposed in chamber A. After a suitable interval of a second or two, however, when sufficient pru ure has been built up in chamber B by superhcat or" the water and partial steaming thereof, the pressure within chamber B forces water through the spout l5. After sufficient water has passed into ground containing container 2d, the valve .15 is closed, permitting chambers A and B to be in communication again.

Hood Zal acts as safety trap catching any steam bubbles which may have escaped into chamber A during the superheating of the water in chamber E and retains them until they dissolv Chamber A is vented by leaking about the gasket s well as about the top cover d and the tube cap 3l to prevent building up of excessive or hazardous pressures within chamber A, from steam other than that entrapped under hood 24.

Having thus described my invention, what l claim new and desire to secure by Letters Patent is:

ln a device of the character described, a main boiler tank, a partitioning plate suspended in said tank and dividing said tank into upper and lower compartments,

3 an opening in said partitioning plate, an operating shaft extending verticaiy through said partitioning plate and terminating in the handle, a movable cover overlying said opening and attached to said shaft, a vaive inside the lower of said compartments adapted to be operated by said shaft, a spout for said valve terminating on the outside of said tank, an inverted funnel hood attached to said shaft and overlying the opening in said partitioning plate, heating means for boiling the liquid in the lower compartment, the construction and arrangement Y being such that rotation of the shaft to cover the opening in the partitioning plate by said cover concurrently opens said valve.
